Matrix Transfer of elements

I had asked similar to this before but had not given enough details. So will try again. I am trying to determine the lowest potential path between 2 points search start and search goal. My path matrix is a 60X2 called path and my source matrix from which I derive my lowest potential cell is 3x3. Once I derive the lowest potential cell in the 3X3 matrix sample8, I transfer the index of this to path. I tried the foll code but get error: :"In an assignment A(:) = B, the number of elements in A and B must be the same." Did some checking and believe this is caused by the line - path(i)=SearchStart;(SearchStart=[3,7] declared earlier in my code.)Thanks for any help provided.

i=1;
 path = inf(60,2);
 path(i)=SearchStart;
 sample8=inf(3,3);

Did you mean to assign the entire row? E.g., this?

 path(i,:)=SearchStart;

Just guessing here since SearchStart is a 1x2 matrix.

Yes. The x,y coordinates of successive points with the least potential to be transferred from sample8 to path i.e. the first point is SearchStart which has coordinates [3,7], this is transferred to sample8; then the next min point is calculated in sample8 and then put in path and so on.
